Question
**Methylamine, CH₃NH₂, is a weak base (pK₆ = 3.36).**

**Which of the following acids is sufficiently strong to protonate methylamine to an extent greater than 50% at 25°C? (pKa for each acid is given)**

- HIO (10.70)
- H₂O (15.7)
- H₂S (7.04)
- CH₃CH₂OH (-> CH₃CH₂O⁻) (15.9)

**Reminder: pKa + pK₆ = 14.00 (25°C)**

**Select one:**

- A. H₂S only
- B. HIO and H₂S
- C. H₂O only
- D. H₂S and H₂O
- E. HIO only

This information is presented as a question to assess understanding of acid-base reactions, specifically the ability to identify which acids are strong enough to protonate methylamine based on given pKa values. The reminder of pKa + pK₆ = 14.00 indicates the use of the water ion product to compare acid and base strengths.
